Title: Improvements in or relating to apparatus for hoisting and tipping railway wagons
IPC: B65G67/00
Filed: 1922-07-17
Abstract: 209,444. Mitchell, r. G. July 17, 1922. Rotary tipplers.- Relates to apparatus of the kind in which a cradle c carrying the wagon is hoisted in guides b and is tipped by the hoisting ropes when bearing surfaces on the cradle come against bearing surfaces on the guides b. To prevent shock, the bearing members on the cradle are out of hue with the fixed pivots and are brought up to the pivots with decreasing velocity as the cradle approaches the top of the guides. As shown in Figs. 2, 3, and 9, rollers 1, 2, 3, 4 are provided on the cradle structure c which co-operate with guides t<1>, u, v and w respectively at the top of the vertical guides b so as to bring the bearing rollers 1 against concave surfaces o<2> on keepers, Fig. 3, at the top of the guides b. The rollers 3 engage recesses o<3> in the keepers so that the latter turn about the axis of the pin p when the hoisting chains are further raised to tip the cradle. The rollers 3 prevent tilting of the cradle during lifting. In a modification, a similar set of rollers and guides brings a concave bearing surface on the cradle against a fixed fulcrum pin at the top of the guides h. The arrangement of the winding drums f and the wagon holding means i, j, may be as described in Specifications 194,811 and 195,846 respectively. To limit the backward movement of the holding bar i, a frame 5 is provided, extending above the top of the guides b. The cradle and balance weights may move in inclined instead of vertical paths. The Provisional Specification describes hand- or spring-actuated stops or chocks which are inoperative when the cradle is in the normal position, but are moved into engagement with the wheels of the wagon when the cradle rises. Staiths and elevated structures.-The hoisting and tipping apparatus may be duplicated, the wagons emptying into a bunker 6 between the two sets, and the towers may be connected by gangways 9.

Filed: 1928-07-06
Abstract: 316,750. Boot's Pure Drug Co., Ltd., and Marshall, J. July 6, 1928. Acyl and alkyl phenols.-Acyl derivatives of monoalkyl ethers of catechol are obtained by heating the said monoalkyl ethers or their esters with fatty acids in the presence of phosphorus oxychloride. The acyl group takes up the pposition to the alkoxyl group. In examples, 5- propionylguaiacol is made from guaiacol or guaiacol propionate and propionic acid, the propionyl ester of 5-propionyl guaiacol being formed as an intermediate product, and 5-acetylguaiacol from guaiacol and acetic acid. The acyl groups may be reduced to alkyl groups, for example, by the Clemmensen process, with amalgamated zinc and hydrochloric acid. The products are of therapeutic value.

Title: Gas discharge display panel
IPC: H01J17/49
Filed: 1973-04-25
Abstract: 1438142 Making gas discharge display panels INTERNATIONAL BUSINESS MACHINES CORP 25 April 1973 [8 May 1972] 19720/73 Heading C1M [Also in Division H1] The walls 10 and 11 of a gas discharge display panel are spaced apart by two orthogonal sets of contacting spacing rods 21 and 22. Passivated metallized conductor arrays 14 and 15 formed on the glass plates 10 and 11 are covered with glass coatings 16 and 17. The spacing rods 21 and 22 are also of glass. The panel is manufactured by superposing the components with a frame of glass rods (Fig. 3, not shown) in place of the seal 20<SP>1</SP>, each rod being of larger diameter than the combined diameters of rods 21 and 22 and of a lower melting point glass than the spacing rods 21 and 22 and the coatings 16 and 17. The parts are then heated in a vacuum furnace to soften the frame rods which deform until coating 16 contacts rods 21. The assembly is then cooled to form the seal 20<SP>1</SP>. In an alternative method (Fig. 4, not shown) the coatings 16 and 17 are also of lower melting point glass than the rods 21 and 22 which therefore sink into the coatings until they contact the plates 10 and 11.

Abstract: 1,189,377. Substation anti-sidetone network. WESTERN ELECTRIC CO Inc. 28 April, 1967 [6 May 1966] No. 19750/67 Headings H4K and H4R. A telephone subset contains an anti-sidetone resistive hybrid bridge and a receiver which is arranged to be connected directly to telephone line and to receive via transistor amplifier the out-of-balance currents produced in the hybrid bridge by speech-signals arriving on the line; the bridge -remaining balanced and the receiver unaffected upon transmission from the subset. In Fig. 4, the line impedance Z L , the resistors R1 and R2 and non-inductive impedance Z N  form a balanced bridge with the transmitter T effectively connected across one of the resistance arms. Upon transmission from the subset a current is is generated in arm R s  and balanced by a current i N  produced in X N  by the transmitted signals. No current therefore flows through transistor amplifier Q 4 , Q 2  to the receiver R. Upon receiving speech signals over the line no current flows in R s  to balance the current i N  through Z N  which is amplified and applied to the receiver R. By making the amplification of Q 4  and Q 2  large there is little loss of speech signal strength in the bridge and with Z N  and R s  large as well there is little loss in the transmitted signal strength. The input impedance of the speech circuit depends upon Z N  and the amplification of Q 4  and Q 2 .

Patent GB-584983-A (GB)
Title: Improvements in or relating to wringers
IPC: D06F45/18
Filed: 1944-10-14
Abstract: 584,983. Wringers. LOCKWOOD, P. W. Oct. 14, 1944, No. 19865. [Class 138 (ii)] In power-operated wringers where means is provided for releasing the pressure on the rolls and disconnecting the drive between the power and the rolls should the operator's fingers be caught, means is now provided for quickly resetting the mechanism without altering the setting of the pressure spring. The rollers 4, 5 are journalled in bearing blocks 6, 7, 8 and 9 carried in side styles 1 and 2 connected at their lower ends by a trough 3, and a top bar 10 of channelsection has pins 21, Fig. 2, extending into curved slots 22 in the style 2 and at the other end is held in operative position by a link 24 attached thereto having a pin 23 thereon to latch below a lug 25, Figs. 1 and 3, on the housing 26 of the power head, which has slots 27 on each side of the lug 25 for emergency release of the roll pressure. The link 24 carries a pin 28 engaging a slot 29 in a yoke 30 pivotally seated in a hole 31 in the power head housing 26 and embracing a clutch member 14 sliding non- rotatively on a power shaft 13 connected to the power unit. The member 14 clutches the driving shaft to a loose sleeve 14<1> upon it which has sliding non-rotatably on it a clutch member 18 for driving in either direction, through bevel gears 15, 16, a bevel gear 17 connected to the lower roll 5. Plates 19<1> secured to the style 1 are bolted to a yoke 20' rotatably mounted on the sleeve 14', or in an alternative construction, on bearing bushes for the shaft 13 so that the wringer can be swung round the shaft, in an emergency, to allow the pin 23 to pass above the housing 26 releasing the pressure of the spring 12 on the rolls and allowing springs 32, 33 to separate the rolls and free the hand of an operator caught between the rolls. At the same time, after a slight lost motion, the link 24 would raise the clutch 14 and cut off the power drive from roll 5. Correct position of the wringer for work is ensured by a spring-pressed ball 54 in the yoke 20<1> engaging a recess 55 in the fixed support 26 of the hollow shaft 44 supporting the power head. To facilitate resetting of the top bar 10, the pressure, adjusted by a screw 11, is communicated to the leaf spring 12 through a cam 34 eccentric on a spindle 35 which is guided in slots in the top bar 10 and mounted in a bracket 36. A handle on the spindle 35 is turned to slack off'the pressure while resetting the top bar and engaging the pin 23 beneath the lug 25 after which the cam 34 is turned to apply the pressure set by the screw 11. The power head housing is rotatably mounted on the hollow shaft 44 fixed to a washing machine 45 and to prevent the wringer being turned aside while under power a locating stud 48 normally engages a hole in the casing of the machine 45 and can only be raised when an extension 46 on it is opposite gaps in an interlocking disc 51 on the shaft 18<1> which selects the direction of turning of the rolls, the lifting of the stud 48 thus being only possible when the clutch 18 is in neutral no-drive position.

Abstract: 430,386. Nitrogen peroxide; nitric acid; chlorine. KALI - FORSCHUNGS - ANSTALT GES., 5, Schonebergerstrasse, Berlin. July 6, 1934, No. 19881. Convention date, Aug. 5, 1933. Addition to 398,187. [Classes 1 (ii) and 90] In reacting nitrosyl chloride with air or oxygen at ordinary temperature to produce nitrogen peroxide and chlorine as described in the parent Specification, the steps of both the stage leading to the splitting - up of the nitrosyl chloride and the stage leading to the separation of the nitrogen peroxide from the resulting gaseous mixture are employed simultaneously. Preferably, an excess of oxygen is added initially or is maintained by the repeated addition of oxygen throughout the whole washing process. The washing medium may be brought into intimate contact with the products of the reaction in the zone of commencing decomposition, say by sprinkling or as a sprayed mist, for example by atomization by means of the oxygen or air being supplied to the reaction. Concentrated nitric acid may be used as the first washing medium, the nitrogen peroxide being recovered therefrom unaltered after saturation, and the nitric acid being cyclically returned to the process. The remainder of the nitrogen peroxide content of the gases may then be recovered as nitric acid in the manner described in the parent Specification. Reference has been directed by the Comptroller to Specifications 329,200, [Class 1 (ii)], and 398,187 (as open to inspection under Sect. 91 of the Acts).
